Diona Quick TL;DR Support and Healer Build Guide – Version 2.5 – February 2022
UPDATED FOR 2.5 😁!
Table of Contents
- 1 PSA #1: A Support is like eating a hotdog with no condiments. Yeah, it’ll still taste pretty good, but why eat a pretty good hotdog when you can eat a bomb ass hotdog instead?
- 2 PSA #2: Both Diona’s abilities scale off ATK, but her shield and healing do scale off HP, and worth the investment! Literally everything about this character is a cat lovers wet dream
- 3 WEAPONS (Recommended for best Shielding): Sacrificial Bow
- 4 ARTIFACTS (Recommended for best Supporting): Tenacity of the Milleith + Maiden Beloved
PSA #1: A Support is like eating a hotdog with no condiments. Yeah, it’ll still taste pretty good, but why eat a pretty good hotdog when you can eat a bomb ass hotdog instead?

Two ways to use Diona’s E (based on Talent level 8):
- Tap E: Launches 2 paws that deal cryo damage and creates a shield that lasts 4.8s (2.4 x 2)
- Hold E: Launches 5 paws that deal cryo damage and create a shield that lasts 12s (2.4 x 5)
It is highly recommended to level E, as each level increases the shield duration per claw!
IMPORTANT TIP: The cat paws from E have awkward targeting, and will majority of the time hit the same enemy (if lucky nearby since it has a small AoE detonation). So your position is essential. Sometimes, if you’re a bit too far, they won’t event target anything.


Take note that the heal is a bit dangerous, as you’re essentially made to heal next to the enemy (which most likely did the damage to you to begin with). Just be mindful of where the heal lands, and to make sure your shield will remain up to guarantee safety while healing!

Talent Leveling Order: E > Q > Normal (But try to level E and Q equally)
WEAPONS (Recommended for best Shielding): Sacrificial Bow
How do I get it D: ?: It’s time to roll boys (gacha)

Sacrificial Bow makes holding E much more forgiving and helps to extend the shield duration. Essentially you have a higher shield uptime, so if your goal is to provide a shielder — then Sac Bow is your go-to
Favonius Warbow is a strong contender, and does better than Sacrificial Bow if your goal is to turn Diona into an energy orb slot machine. Just remember to take a bit of CRIT% so that you can successfully proc the energy orbs. Ideally not useful unless you have it R3+.
ARTIFACTS (Recommended for best Supporting): Tenacity of the Milleith + Maiden Beloved
How do I get it D: ?: Tenacity at Ridge Watch Domain (AR 30 locked, 20 Resin per run). Maiden Beloved at Valley of Remembrance Domain (AR 30 locked, 20 Resin per run)


You can technically run 4x Maiden, but Diona’s main appeal and strength is her shield, hence why 2x Millelith + 2x Maiden is the most optimal as it benefits both aspects.
If no one else on your team is running it, 4x Noblesse Oblige is an extremely strong set as Diona can perform as an ATK buffer to her team as well.
Keep in mind that Retracing Bolide DOES NOT make the shield stronger for other characters when you swap, unless they have 2x Retracing Bolide equipped as well (which is NOT recommended).
For newer players, you can run 4x Exile early on for the energy regeneration!
Main stats:
Sands | Goblet | Circlet |
---|---|---|
HP% (ER% if you need it) | HP% | Healing Bonus% |
Substats: HP% (for non-HP% main stat) > ER% > flat HP > EM
If you want other characters let me know. Hope this helped. Bye.
I have heard that when levelled and equipped, Diona is a tank that provides regular huge shields making her mostly unkillable – I’m currently levelling Zhongli for a similar role, should I persevere with Zhongli (so sick of mining cor lapis…) or switch to Diona?
Oh my main DPS is Ganyu with an Amos’ Bow, so building my team round her 🙂
Cheers, love the guides ^_^
You can run Diona instead of Zhongli. 100% center your team around what’s available for you. You can always farm up mats for Zhongli slowly for future use, but Diona can also do a hefty job at shielding + healing (plus she’ll fill Cryo resonance)
why crit dmg and rate substats are > than hp/er?
I never noticed I didn’t change that LOL. I usually copy and paste it and edit it per character, but guess I forgot for this one. Thanks for catching it!
No probs mate!
a little error, TotM comes from the ridge watch domain, you put noblesse oblige instead
Oh, thanks for the catch! Tend to have little errors here and there when I update guides haha
Would 4 set Millelith be okay on her?
You wouldn’t gain any benefit from the 4x bonus at all. It’s better to just run 4x Noblesse or 2x Millelith + 2x Maiden
is 4x noblesse or 2x millelith + 2x maiden better?
4x Noblesse is technically better, but if someone is already running it the 2x + 2x set is better off!
Is there any 3 stars bow and craftable 4 stars like prototype crescent/compound bow?
The craftable bows are a waste to use on Diona, but out of 3-star options there is technically the Recurve bow for the HP% it provides
